4-Piece Fuel Injector Set 28308779 — Direct-Fit Common Rail Replacement for Mercedes-Benz OM651 & OM646 Diesel Engines | C-Class, CLS, E-Class, M-Class & SLK

Restore the refined power delivery and exceptional fuel efficiency your Mercedes-Benz diesel is engineered to deliver with this complete set of four brand-new common rail fuel injectors. The OM651 and OM646 are sophisticated BlueTEC diesel engines found across Mercedes-Benz’s most popular model lines — and when injectors wear out, the impact is immediately felt: rough idling that doesn’t suit a Mercedes, hesitation under acceleration, increased fuel consumption, and unwanted black smoke. This matched set of four restores precise high-pressure fuel delivery across all cylinders, bringing your Mercedes-Benz diesel back to the smooth, efficient, and responsive performance it was designed for.
